after aaaaaalmost 3 years of having my boxx i started getting problems. looked like the video card had gone but when i changed it, it was still not working. when i called tech support at boxx the had me check the ram. that seemed to be the problem.
When you say problems do you mean cpu slowdown/under performance or some other type of problem ?
There are several things to try in this case:
(*) Try to render without texture maps;
(*) Try to render without the proxies;
(*) Try to render with the proxies, but with larget dynamic memory limit.
Best regards,
